Do They Test for Infection in an Autopsy?

Last Editorial Review: 8/31/2017

Ask the experts

When doing an autopsy, is it possible to test for infection (urinary tract infection, sepsis)?

Doctor's response

Yes, signs of infection are generally apparent during observation of the internal organs both with the naked eye and on microscopic slides of tissue samples. Large collections of pus, such as abscesses, may be seen. While it often is possible to detect if an infection is present, microscopic analysis and/or cultures of blood and body fluids are required to determine exactly which organism is responsible for the infection. Cultures of blood, which would reveal the presence of an infection in the blood stream (sepsis) are routinely done in many hospital autopsy services. Additionally, cultures to identify infectious organisms usually are performed if there is an area of the body that is suspicious for infection.
